Online double conversion

• Online Double Conversion design helps to output a pure sine wave ,which is immune from the UPS input, so that the load can run steadily.
• UPS transfers  among different working mode  without  output  interruption,  thereby powering the load uninterruptedly.

Full DSP control

• Full DSP Control avoids the risks caused by analog devices failure and makes the control system more stable and reliable.

High power factor

• The output power factor up to 0.9 better matches the load. The input power factor 0.98 with filter helps to improve the efficiency, reduce the harmonic pollution to the Grid and  lower the UPS running cost.

Wide input adaptability

•  The range of AC input voltage is (380Va1 400Vac/415Vac) (-25%/+20%), minimizing transfer to  battery mode,  thereby greatly prolonging the battery life.
• Wide   input  frequency  ranging  from 45Hz to 65Hz, ensures stability of UPS while generator connected.

Optimized battery management

• Intelligent battery management system and advanced  battery auto float/boost  charge technology, reduces the frequency of battery maintenance, greatly improves the battery efficiency and extends battery life. 
• Battery  discharge  time  prediction:  the system will display the backup time of battery calculated by discharge current and voltage.
• Battery self-test: battery is automatically tested at regular intervals
• Flexible battery configuration ranging from 360-408Vdc / 480Vdc.

N+X parallel redundancy

• N+X parallel redundant design, up to 6 units available, makes  the configuration more flexible.
• Any unit in parallel system fails, the faulty one will automatically cut off the output, and the load will be powered by the remained units.
• It is easy to configure the parallel system just by connecting the parallel cables and doing proper settings.
• Non-fixed Master-Slave relationship: Among several UPS in parallel, the unit startup first is Master UPS, the others are Slave. The master and sieve may be exchanged.

Strong overload capability

• 110% / 125% 1150% overload for 60min I 10min 11 min.

Power walk in

• Specially designed power walk in function, in which rectifier of each unit in parallel system will be turned on in sequence at intervals to avoid the sudden load on the generator,
  thereby reducing the cost of the generator required.

Generator mode

• Set the maximum output power of the generator when a smaller one than needed is employed to extend the battery duration time. In this case, the load is supplied by both the generator and battery.

LBS synchronization

• Synchronize the output of the two independent UPS systems (single unit or parallel) even when the two systems are operating on different modes (bypass/inverter) or on battery.

Multi-protection

• Self-diagnosis function will  take  place before start-up for safety.
• Multi-protection: AC input under/over voltage, overload, short-circuit, over-current, over bus voltage, over-temperature, fan failure, auxiliary power failure, battery under voltage, battery over-charge and so on.

EPO function

• A concave red EPO button with transparent cover is embodied in the LCD control panel for emergency power off.

User-friendly network management

• Chinese/English LCD and LED mimic diagram: real time operation parameters and status
• RS232 & RS485 communication ports: for local monitor with corresponding software, and MODBUS protocol is optional.
• SNMP adapter (optional): for remote monitor through network

Dry contacts for additional monitoring:

a) UPS on Inverter

b) Mains input failure

c) remote EPO

d) Battery low voltage alarm

e) UPS fault

f) UPS alarm

g)UPS on battery

h) UPS on bypass
Note: d)–h) optional
